Mn'cHlNsoN REVERSIHG GEARING MECHANISM FOR STRAW STACKERS Filed May 22; 1922 2 Sheets-Sheet 2 J- www HW www These pins are arranged to alternately engage opposite sides ot the trip lever 42 which is pivoted as at i3 upon the plate 8. This trip lever is'provided with a slot ll through which the shaft 2O extends, spaced collars 4:5 and 45a being lined upon said shaft and arranged vto be alternately engaged by the trip lever.

rihe lower end of the trip lever is provided with a wrist pin 4:6 through which a rod l? e2;- tends, said rod being pivoted at its lower en d as at i8 to a bracket 49 upon the plate 8, and pro 7ided near the pivotal point with a shoulder or collar 50, a coil spring 51 being interposed between said collar and the washer 52, which is rheld in engagement with the wrist pin by means of said spring.

The operation of the device is as follows: assuming the members to be in the position shown in Figs. l and 2, the double clutch 2e is shown engaging the clutch lmember of the bevel pinion 26, the trip lever l2 having just been moved into the present position by the engagement of the pin il therewith, the trip lever being thrown against the collar 5&5, sliding the shat't 2O outward and drawing the double ended clutch 2e out ot engagement with the pinion 2 and into engagement with the; pinion 25, reversing the direction of movement et the gear 28 and through the worm 39 reversing the movement ot the gear 5 w rich carries the stacker tube.

The gear 5 will then travel in this direction, oscillating the stacker tube until the other pin ll engages the opposite side of thetrip lever 42, throwing'the trip lever into engagement with the, cellar 45a, sliding the shaft 2O inward and moving the clutch 2li out otv .igagement with the pinion 26 and into engagement with the pinion 27, reversing the direction of rotation oi the gear 28, and through the worm 39 reversingthe direction or' the gear 5. The

As rijne' 5i androd 47 will uicklv throw the trip lever'ever center and hold it in this posi? tion nntil ythe lever is again engaged by: one oithe pins 41 and reversed.

This'osoillation of the stacker tube will continue automatically during the time that the threshing machineis operated, unless it is desired te hold the stacker tube at any onev place for a timewhen the clutch 35 maybe disengaged, stopping the rotation orn the worinSS).

jacent to said wheel, a drive shaft j'ournaled in said plate, a worm upon the drive shaft, a beveled gear operatively connected to said wheel and journaled in the bracket plate, spaced bearing arms upon the bracket plate, aA tubular shalt located at right angles to the anis of said beveled gear,l and journaled in said bearing arms, a worm wheel upon said tubular shalt meshing with said worm, a pair oi beveled pinions loosely mounted upon said tabular shalt and meshing with said beveled gear,a solidi shaft slidably mounted within thetubular shaft, said tubular shaft being slotted, a double clutch member slidably mounten up" n the tubular shaft, a radial pin connecting the solid shaft' and double clutch member, the tubular'shatt being thus continuously driven, in one direction, 'spaced col lars upon thev solid shaft, a spring toggle trip lever arranged to engage each ot said collars, pins; upon the wheel Y'r'or alternately throwing the trip lever into engagement with each col? lar tor sliding the solid shai't in opposite directions to move the double clutch member into engagement with each ofthe beveled pinAN ions.

ln a reversing gearing for a straw tube or the like having a wheel 'forming the pivotal support thereof, a bracket plate mounted adj aoent to said wheel, a drive shaft ournaled in said plate, a worm upon the drive shaft, a beveled gear operatively "connected to said wheel "and journaled in the bracket plate, spaced bearing arms upon the bracket plate, a tubular shait located atvright angles` to the avis ot said beveled gear, and jonrnaled in said bearing arms, a worm wheel upon said tubular shaft meshing with said worm, a pair oi beveled pinions loosely mounted upon said tubular shaft and meshing with said beveled gear, a solid shaft slidably mounted within the tubuiarshailtfsaid tubular shaft being slotted, a double clutch member slidabl'y` mounted upon the tubular shaft, a radial pin connecting the solid shaft and double clutch member in one direction, spaced collars upon the solid shaft, a trip lever'arranged to engage each otsaid collars, pins upon the wheel for alternately throw-ing the trip lever into engagement with each collar 'for sliding the solidshait in opposite directions to lmove the Adouble clutch member into engagement with each ofthe beveled pinions and spring means upon kthe bracket plate, for quickly throwing the trip lever to reverse position when engaged by one of said pinsy and for holding thev trip lever in each position.
